Hi all,
i've been working on getting my PID based BIAB rig up and running, and thought i'd start working on a very simple PID program generator.
It's just a spreadsheet i thought i'd throw up here on AHB for those so inclined that may like to use.
It caters for a simple, single step mash, with the option for a mashout or not.
Just enter the details in the boxes and then program the PID with the steps displayed in the right hand side chart.
It automatically adds 2 degrees to the first step, as this would replicate a similar strike temp before doughing in for a BIAB rig. If your rig is different in this regard, just change the +value in cell E4.
Put your PID into "stop" mode (hold down the up arrow) before you add grain to make the controller stop heating. Then just run the controller from CO2 mash step onward.
I have attached some pics....
With Mashout:
No Mashout:
If you never mashout, just bump the lower programs up to marry with the last blue mash step.
I know it's very basic, but i thought it may be helpful for some (like me) who are new to this whole pid programming thing.
I intend to add more mash steps, or someone else can do it if you feel like it. Not fussed.
I have also thrown this spreadsheet in my phone, tablet, brewery combrewtor for easy access on brewday.
Any thoughts and opinions welcome!
